Love blue tiles. Depending on how much sun and how hot your pool gets in the summer should dictate what color it is. We live in Arizona, so cool blues work best. Our neighbor has brown tile and a dark pebble tech pool. Looks like a swimming hole and gets really hot - 94% water in the summer. They obviously didn't think it through.

Paint your house and ceiling first. You are probably asking for trouble if you put the floors down only to paint over the top of them. If you can, remove the tiles in the kitchen and paint just behind the line of the splashback too. Once painting is done replace kitchen benchtop then splashback. I would call the bathroom its own job and do it individually, unless you only need to paint the ceiling and if a tiler doesn't need to be brought in for anything else in the house? A lot of bathrooms now are getting tiled from floor to the ceiling if this is the case, paint the ceiling first, then tile. If walls need to be painted, it wouldn't really matter if you did them first or last, though if you did it first expect to do some touch-ups. I guess if you really wanted, you could do the first coat before tiles then second after... I don't exactly like stopping and starting painting, so I would do the walls (if they needed to be done) in one hit, after its been tiled. Well that's the order in which I would do everything... Really, for what you're asking, the painting could be done at anytime, but to make life easy on yourself, I would definitely recommend doing it before the floor.

I am trying to source (in New Zealand) a shower tray which will fit into my alcove Sized 1900x1000 for the shower. Thus far for that size (and I have searched online and in merchants) found only tiled over solution to completely cover floor space. Not totally happy to have this as feel that tiles will be slippery when wet. Whereas have found smaller acrylic trays that are described as non slip even tho they are smooth. Can anyone suggest a supplier that they have used for trays and hinged/pivot doors of the size I require? Or if place a shorter acrylic tray to the length (probably 1200mm) of the glass wall, as will create a walkin with what do I cover the remaining 700mm of the alcove floor? The bathroom floor will not be any kind of tile, more likely to be a textured vinyl plank.

My comment would be that fluted glass would be a bit harder to keep clean??
